Barnoldby le Beck is a village and civil parish in North East Lincolnshire, England, It is situated just east of the A18 and is close to the village of Waltham and the town of Grimsby.

The name Barnoldby le Beck has origins in the Norse settlement of North East Lincolnshire. The affix by means a farm or settlement and is preceded by the modern phrasing of the personal name Bjǫrnulfr. While le beck reflects the Scandinavian word bekkr which means stream.

In the Domesday Book of 1086, Barnoldby le Beck was a large village with 9 smallholders, 26 freeman, 12 ploughlands and a meadow of 200 acres. In 1066, the lord was Ralph the Staller, a constable of Edward the Confessor, and in 1086, the lord and tenant in chief was Alan Rufus.

Early land holders in the Middle Ages included the Abbot of Grimsby, John Yarborough and Geoffrey le Scrope.

Following the Enclosure of common lands in 1769 there were 12 landholders, including the Dashwood, Hewson and Bonsor families.

Following the English Civil War, Anthony Harewood, the Royalist rector of the church of St. Helen's was replaced by a Puritan minister at the direction of the Earl of Manchester.
